Should I Claim 0 or 1 on my W4 Allowances Taxes?

Have you asked yourself the following question?

Should I claim 0 or 1 or even 2 on my W4?

Keep on reading to find out what you should claim.

One of the first things you do when you start a new job is to fill out your W-4.

What is a W-4 form anyways?

Formally known as the Employee Withholding Allowance Certificate, a W-4 tells your employer how many allowances you’re claiming which determines how much federal income tax they need to deduct from your pay.

The more allowances you claim, the more money you’ll get each paycheck but, in return, you’ll receive a lower tax refund, if any, at the end of the year.

The number you claim affects your take-home pay and your tax refund so it’s important not to write down just any number but to assess your situation and make a smart financial decision.

This is what a W-4 form looks like:

How many allowances can I claim?

How many allowances you can claim is determined by your filing status, how many – if any – dependents you have, and how many jobs you have.

But keep in mind, that you don’t have to claim all the allowances you’re entitled to. In fact, depending on your situation, it might be in your best interest to claim 0, 1 or more than 1.

Claiming 0 Allowances

Claiming zero allowances means that the maximum amount of taxes will be withheld from your paycheck. This means that come tax season, you’ll most likely get a nice big tax refund.

When should you claim 0 allowances?

There are only a few situations where I would recommend you claim zero allowances on your W-4 form.

  • If someone is claiming you as a dependent. When someone claims you as a dependent, they get the benefit of your personal exemption. Which means their tax burden will be lowered, but yours will be a little higher which is why you should claim zero allowances. This doesn’t necessarily mean you won’t get a tax refund, however.
  • If you know you’re bad at saving and want to save on easy mode. Despite what some people may believe, your tax refund isn’t “free money”. Getting a tax refund means you’re overpaying on your taxes every paycheck and at the end of the tax year, the IRS returns the extra money you paid. This means you can easily “trick” yourself into saving money by claiming 0 allowances and then have the IRS e-deposit your tax refund into a savings account. Of course, this is not ideal, because you’re not earning interest on that money for that whole year. But it’s a great way to force yourself to save.

Claiming 1 Allowance

Claiming 1 allowance means that a little less tax will be withheld from your paycheck than if you claimed 0 allowances.

Here’s when I would recommend you claim one allowance.

  • If you’re filing status is single this is the safe choice. If you’re single and barring any complicated tax situations, you’ll most likely still receive a refund. Though it will be smaller than if you claim zero allowances. This is the most common number of allowances single people claim.

Claiming 2 Allowances

You probably know the drill by now. Claiming two allowances means even less tax will be withheld from every paycheck.

Here are the situations in which you should claim two allowances:

  • If you’re filing status is single and you want to get as close as possible to break-even as possible (getting a $0 tax refund). However, depending on your tax situation, you may end up owing a little bit. If your financial health is good, this is the number of tax allowances I recommend that you claim.
  • If you have two jobs and your filing status is single, you’ll end up filling out a W-4 for each job. You can claim 1 allowance on each W-4 OR you can claim 2 allowances on one W-4 and 0 on the other.
  • If you’re married with no kids. If you file jointly, you can claim two allowances. One for you and one for your spouse. Not sure if you should file jointly or file separately? Here’s a good primer by TurboTax.

Claiming 3 Or More Allowances

You can claim more than 2 allowances if you’re married and have one child or more. Basically, you get one allowance per child so:

  • Claim 3 allowances if you’re married and have 1 child
  • Claim 4 allowances if you’re married and have 2 children
  • You can guess the rest

Can I claim 99 allowances?

You technically can claim 99 allowances BUT you definitely shouldn’t. According to the IRS, 10 million people underpaid their taxes in 2015 and ended up having to pay a hefty fine.

Income tax is a pay-as-you-go tax which means you can’t wait until the end of the year to pay all your taxes as a lump sum. You have to either withhold enough tax from each paycheck or make quarterly estimated tax payments. Withholding your taxes by filling out a W-4 form with the correct amount of allowances is the easiest way to avoid underpaying.

So should I claim 0 or 1 allowance?

Most people claim 1 or 2 allowances

As I mentioned earlier in this article, depending on your specific situation, it may be beneficial to not claim as many allowances as you’re entitled to.

The more allowances you claim, the less tax is withheld. This is a good situation to be in if you’re in good financial health – as long as you don’t end up owing too much tax.

But, if you’re living paycheck to paycheck and don’t have any kind of emergency fund, then claiming fewer allowances than you’re entitled to may be a good option. This means you’ll be receiving less each paycheck but at the end of the year, you’ll receive all the extra money that was withheld as a lump sum.

You can use your tax refund to build up your emergency fund or to pay off any consumer debt. You’re basically forcing yourself to save money from each paycheck. Just don’t treat your tax refund as a “bonus”.

You have to decide for yourself whether you want to “fool” yourself into savings or not by claiming extra allowances.

Can I change my W-4 allowance?

You can change the number of allowances you claim at any time. Just fill out a new W-4 and give it your employer.

There are some life events that happen which change the number of allowances you should claim. Getting married and having a kid are the two most common of these life events.

Tax Resources

I hope I answered your question of:  should I claim 0 or 1 on my W-4?

Still unsure about how many allowances you are entitled to?

One of the best tools to use to figure out how many W-4 allowances you should claim is the IRS Withholding Calculator.

You should also check out IRS Publication 505. It’s the official instructions from the IRS to determine your allowances and estimating your taxes.

TurboTax also has a great suite of tax tools which can help you with a variety of tasks including calculating how many allowances you can claim.

2019 W4 Guide

Form W-4 Tax

Filling out your W4 can be a fairly simple process. As I mentioned earlier in the article, the purpose of the W4 is to designate the amount of tax withholdings that your employer should take from your paycheck.

If you don’t fill out your W4 correctly, or if you don’t take the right number of claims, you could overpay income taxes or worse, under pay income taxes.

Neither of these situations are ideal, so knowing the right way to fill out your W4 can be vitally important for your pocketbook now and into the future.

It can be easy to fill out the W4 form, if you take some time to read and understand the withholding and deductions information.

However, if you have never filled out one of these forms, it can be confusing the first time. I felt it was important to give some helpful information on how to fill out the 2019 W4 form. Keep in mind this information is only applicable for 2019 form, the form for 2020 may have new requirements.

The IRS has provided a personal allowances form that you should use to assist you in filling out the allowances section of the W4.

Remember, the number of allowances you take, will change the amount of withholdings that are taken from your paycheck. The fewer allowance, the more money that is withheld.

Most people claim 1 or 2 allowances. This will ensure that you pay enough income tax, without substantially overpaying.

However, if you need more money to stay in your paycheck, and you have kids or a spouse to support, it may be logical to claim more than these common allowance amounts.

On the flipside, if you have other income, that isn’t subject to income taxes (for example your spouse works as a contractor and uses a 1099 form), you may want to consider keeping your allowance at 1, or claiming 0 on your tax form may be appropriate.

The personal allowances worksheet that comes with your W4 is a great way to calculate your allowances. However, many people find that this tool is difficult to understand.

There are lots of other resources on the internet to help you decipher the personal allowances worksheet, and there are lots of calculators that will help you as well.

To help you through this process, I’ve come up with a step-by-step guide to filling out your W4 form and the personal allowances worksheet.

  1. Start with your name. This is pretty easy, and it should feel intuitive. However, many people forget that you must use your legal name, or the name associated with your social security number. Don’t use nicknames or aliases. Also, remember, if you’ve gotten married and changed your name, you need to update this form with the correct information.
  2. Your social security number. Again, pretty obvious. If you are a contractor, or need to claim taxes for a business, do not use the W4, you’ll need to use a 1099 and your EIN. The W4 is for individuals working as a regular employee only. If you’re filling this form out, use your social security number only.
  3. Address – Use the same address that you would associate with your tax filings.
  4. Marital Status – If you’re single, mark “single”. If you’re married and file joint taxes, mark “married”. If you’re married, but file separate taxes, mark “married but withhold at higher single rate”.
  5. Allowances – This section is confusing, and you should follow the personal allowance worksheet to ensure that you calculate the right number of allowances. If you find that this form is confusing, websites like TurboTax and even the IRS have handy calculators that you can use. Just remember, if you claim too many allowances, you may risk underpayment and if you claim to few, you may overpay.

There are three different worksheets that come in the personal allowances section of the W4 form. We’ll cover these more in-depth in the Personal Allowances section of this article. However, here’s some basic information to help you with filling out the form.

The first section of the worksheet is for personal allowances. If you are filing as a single person, this form is pretty straight forward, enter one in line A.

If you are married, or have children, you’ll need to fill in lines B through G and then calculate the number of allowances in line H. Don’t be surprised if the number is pretty big, especially if you have kids or are married. You’ll adjust this number further on the Two-Earners/Multiple Jobs worksheet.

The calculation from line H, if you are single, will be used in box 5 on the W4. If you are married, you’ll need to use line H on the Two-Earners form, on line 1. If you have multiple jobs, or both you and your spouse work, you’ll need to do further calculations on the Two-Earners form.

After you’ve entered the number of deductions from like H on your personal allowances form to the line 1, you’ll need to find the adjustment factor for the lowest paying job in the household. This number is found in table 1 of the worksheet.

Enter the adjustment number in line 2. Then, subtract line 2 from line 1, only if line two is less than line 1. If line 2 is more, you’ll need to enter “0” in box 5 of the W4 form, and calculate the withholdings using Table 2 and the calculations found on the two income form, lines 4 through 9. This amount will then be entered on the W4 in box 6.

If you follow the instructions on the worksheets, or use an online calculator, you should be able to correctly calculate the right number of withholdings.

Personal Allowances

Personal Allowance

The IRS has provided a personal allowances form that you should use to assist you in filling out the allowances section of the W4.

Remember, the number of allowances you take, will change the amount of withholdings that are taken from your paycheck. The fewer allowance, the more money that is withheld.

Most people claim at least one allowance. Claiming one on your W4, will ensure that you pay enough income tax, without substantially overpaying. However, if you need more money to stay in your paycheck, and you have kids or a spouse to support, it may be logical to claim more than one allowance.

On the flipside, if you have other income, that isn’t subject to income taxes (for example your spouse works as a contractor and uses a 1099 form), you may want to consider keeping your personal allowance low, at either 1 or 2, on your tax withholding form.

However, it’s a good idea to use the personal allowances worksheet provided with the W4 to make the correct claim.

Just remember, if you’re claiming fewer allowances than you need, you’ll have less money in your pocket each month. And while a tax refund is a nice surprise, the real goal with your income tax withholdings is to pay just the right amount, with no refund and no tax bill.

One question that I am often asked is how to make a personal allowances worksheet. Of course, this is a possibility, and spreadsheet programs like

Excel or Numbers (for you Apple fans), are a good way to create your own calculator. However, you’ll probably spend more time creating your own worksheet, than it would take to find and use one already available on-line.

It’s also important to understand that the tax code changes each year, and so do the W4 withholding forms. If you create your own personal allowances calculator, you’ll have to understand the tax code, and update your calculator each year. Again, it may not be worth your time to go through this effort, with so many options available on the internet.

I’ve compiled a list of some of the most intuitive personal allowance calculators that are available on the internet. Keep in mind, some of these are created by companies that sell tax preparation products, so they may try and sell you their wares, if you don’t love these kind of websites, there are plenty of other options on-line, you’ll just need to do your research.


This is probably your best bet. Get the right number, from the source. It is pretty simple to follow, and in theory, if you provide the right information, you should get the right withholding number each year. I ran the calculator for my income, and what I did find is that instead of providing a number of allowances, it provided me with a dollar amount. You can use this number on the W4 in box 6 instead of an allowances number.


Similar to the IRS calculator, this one will tell you how much you can expect to pay on each paycheck, and how that payment, falls into the category of under or overpayment. The nice thing about this calculator is that it actually takes into account some of the common tax deductions like mortgage interest and student loan or tuition payments. H&R Block has a very similar calculator.


This calculator isn’t as intuitive as the ones from the IRS or TurboTax/H&R Block. However, it isn’t from a company trying to sell you something, or the federal government, so it might be more appealing to some users.

Can I Claim 2 on my W4?

Claim 2 on my W4

It certainly is appropriate to claim 2 on your W4 form in many cases. If you are married and filing jointly and you both are employed, and you have kids to claim, the personal allowance worksheet may tell you that 2 is the right number of allowances for your situation.

Two allowances, is actually the recommended number of allowances for most married people.

However, just because the personal allowance worksheet tells you that you that 2 allowances is the right claim, you may want to claim more or even less, than what is recommended.

Keep in mind, and I mentioned this earlier in this article, there are some benefits and downfalls to claiming more or less.

If you need to keep a bit more money in your monthly paycheck, you may want to claim more, and this can be handy for some people that are living paycheck to paycheck.

Just keep in mind that claiming more allowances than you are actually entitled to, may mean a hefty tax bill at the end of the year.

If you don’t want to risk a tax bill, you may want to pay more taxes now, and claim fewer allowances. This will likely result in a tax refund, which can easily be deposited into a savings account or used for other expenses.

Keep in mind however, your tax contributions aren’t a good “savings account”, there are better ways to save money, than to pay more each month in taxes.

What is the average number of claims on W4?

Average Claim on my W4

There really isn’t good information available on what claims are most commonly used on withholding forms. However, we do know that 0 and 1 are really popular options for people with a variety of tax situations.

It seems that lots of people, though able to take more allowances on their taxes, choose to take fewer than they should or could.

There is certainly some concern about that unexpected tax bill at the end of the year, and if you’re living on a budget, it might be easier to take a reduction in your monthly income, that you plan around, than try to figure out how to pay a tax bill come April 15th.

Getting a tax refund is another reason that 0 and 1 claims are so popular. The reality here is that paying too much in taxes is just as impractical as not paying enough.

However, many people would much rather overpay, and get a refund, than try to save money each month, or do the work to have neither a refund or a tax bill at the end of the year. Of course this is the ideal situation, but so frequently tax payers see the refund as a great savings opportunity.

What to do when you’ve underpaid your taxes?

underpaid your tax

Underpayment of your taxes isn’t a great situation to be in.

First of all, no one loves to cut a check to the Federal government on April 15th.

With so many people living paycheck to paycheck, a tax bill can be a huge burden, especially if you have limited savings.

Furthermore, depending on the amount you’ve underpaid, you may be subject to tax penalties, or required to pay quarterly payments the following tax year. No matter how you look at it, a tax underpayment is not a good thing. Here are some steps you can take if you underpaid your taxes.

  1. Don’t skip making your tax payment – This can result in more penalties, and a larger tax bill in the future. The first thing you need to do when you’ve underpaid your taxes, is to make sure you resolve the issue and pay your tax bill.
  2. Pay any penalties – If your underpayment is substantial, you may be assessed penalties. It’s a hard pill to swallow, but make sure you pay any penalties that may be assessed. Failing to pay penalties may result in legal action. The cost to hire a tax attorney will certainly be more than any tax penalties that you’ve assessed.
  3. Consider quarterly tax payments – This may be a suggestion or required depending on how much you underpaid. If you’re underpayment is small, you may just need to adjust your W4. However, if your underpayment is substantial, you may be required to make quarterly tax payments to resolve any future underpayments. Regardless, you’ll still be paying income taxes on your monthly pay, on top of any quarterly payments.
  4. Adjust your W4 – Once you know how much you’ve underpaid, you’ll probably want to go back and adjust your W4 form with your employer. It’s important to remember that you can adjust your W4 at any time in the year, and you can change it as frequently as you would like.
  5. Consult with a tax professional – If you’ve been doing your own taxes, and you aren’t sure why you ended up with an underpayment, it might be time to hire a professional. Until you get your tax situation back in order, a trained tax professional can guide you through the steps you need to take to avoid underpayment and potential penalties in the future. Taxes can be confusing, and so can the W4, so if you’re not sure what to do, find a professional to help.

While any accountant will tell you that the goal with income taxes is to have neither a bill nor a refund, it’s a much easier pill to swallow to take more taxes out over the year, than to pay a big tax bill in April.

Adjust your allowances accordingly, so that you can eliminate the worry of underpayment in the future.

Do claims affects your credit score in any way?

credit scores

The general answer to this question is, no.

The amount of allowances or claims that you take on your W4 will not impact your credit score directly.

The IRS doesn’t report your tax bill or your withholdings to the credit bureaus.

However, the amount you claim can have an indirect impact on your credit score, especially if you underpaid your taxes, and have a large tax bill in April.

If you don’t have enough savings to pay your tax bill, you may need to rely on mechanisms to pay your taxes that can directly impact your credit score however. Some people rely on personal loans or credit cards to pay their tax bill. While these can ease the burden of a large, one-time tax bill, by spreading the payments out over time, they can also have negative impacts on your credit score.

Taking out loans can reduce your available income or increase your debt to income ratio. This can have a negative impact on your credit score.

The same is true if you’re paying a large tax bill on a credit card. Using a large portion of the available credit on a credit card can reduce your credit utilization ratio, and reduce your credit score. Using a credit card to pay your tax bill is a safe option if you plan on paying off the debt quickly. However, this isn’t often the case.

Another way that your credit score can be impacted by your W4 claims is if you don’t pay your tax bill or penalties. In this case, the IRS may impose a Tax Lien on your property or wages.

Tax liens will be reflected on your credit report, and can have a substantial negative effect on your credit score. If you do underpay your taxes, it is never a good idea to avoid payment.

The last way that your claims could indirectly impact your credit score, is if you should have to file bankruptcy to handle a tax bill, tax penalties, or a tax lien.

Bankruptcies can sit on your credit report for an extended period, and can have a long lasting impact on your credit score and credit report.

If you should find yourself with a large underpayment, and you want to avoid the potential credit score implications by taking out a loan or using a credit card, contact the IRS. While we all think they are scary, believe it or not, they do understand that hardship happens.

The IRS can work with you on a payment plan to help you work through your tax bill in a manner that is more affordable. You may even be able to get a reduction in your tax bill by working with the IRS.

These options are great because they help you resolve your underpayment, while at the same time, protecting your credit score, and leaving your credit available for other expenses or needs.

Finally, remember, if you’ve ended up with a big tax bill, and you want to avoid the potential credit report burdens in the future, take the time to adjust your W4 claims.

This is the best way you can avoid the potential tax bill, and keep the IRS out of your checkbook and your credit score.
